River Model

Good afternoon, big fish.
Today we will discuss the River Model used in my classroom.
It is set up into four different pools. Originally, this is how each pool was set up: Pool 1 had nothing in it. Pool 2 had rocks, and 2 brown minnows. Pool 3 had sand, pea gravel, rocks, plants, and 20 ghost shrimp. And Pool 4 had sand, pea gravel, plants, 1 orange and 1 brown minnow, and a cray fish. After a while, we discovered that the cray fish had moved from Pool 3 to Pool 4, and that a brown minnow got caught in a pump and died. :( 

Hopefully this picture will help represent what the river model is like!

Hasta la vista, fishies.
